In the 1930s and 40s, Dr. Saul Hertz revolutionized cancer treatment with his breakthrough research establishing the use of radioactive iodine (RAI) as the cornerstone of nuclear medicine. Today, RAI is the gold standard of targeted cancer therapy. The son of Jewish immigrants to Cleveland, Hertz graduated from Harvard Medical School in 1929 and performed his internship and residency at Cleveland’s Mount Sinai Hospital. As a Jew, Hertz faced many professional challenges that resulted in his contributions being falsely recorded, trivialized, or omitted from medical history. More than 80 years after his research began, his story, achievements, and legacy are now coming to light. Join Barbara Hertz, his daughter, for an illustrated talk on The Hertz family’s origins in Poland, the social biases that impeded Dr. Hertz’s due recognition, and how his medical legacy profoundly impacts current practices.
